Heavy Flow/Periods After IUD

hey! I was on Skyla for about 4 months, and I got off of it due to pain. It was taken out while on my period

I went right on the birth control pill on Sunday, IUD taken out Friday.

Anyways, my period is crazy heavy. Like I am bleeding through Regular and Super Tampons in less than 2 hours. My blood clots literally look like leeches!!

I have also been on birth control since 14, and I’m now 20. Why is my period all of a sudden so heavy? It was not like this before my IUD or on other methods of BC.

Thanks!
